What is a dermatologist?

A dermatologist is a physician specialized in diagnosing and treating conditions of the skin, hair, and nails.

They handle common conditions (acne, dermatitis) as well as mole checks and early skin cancer detection.

When should I see a dermatologist?

  • Acne that isn't improving with over-the-counter products.
  • Spots, moles, or lesions changing in shape, color, or size.
  • Persistent itching, redness, or flaking.
  • Unusual hair loss.
  • Nails changing color or shape.
  • An annual skin check, especially with heavy sun exposure.

Conditions treated

  • Acne and rosacea
  • Dermatitis (atopic, contact, seborrheic)
  • Psoriasis
  • Moles and skin cancer
  • Skin infections (fungal, warts)
  • Hair loss and nail problems

What to expect at your first appointment

The dermatologist examines your skin, and in some cases uses a dermatoscope — a tool that magnifies a lesion — to evaluate it more closely.

If they find something that needs further study, they may take a biopsy (a small skin sample) for analysis.

With a diagnosis in hand, they'll explain treatment, which may include creams, oral medication, in-office procedures, or, if needed, minor surgery.

How to choose the right dermatologist

Look for a dermatologist experienced with your skin type and specific concern, especially if you live in or visit a sunny destination like Puerto Vallarta for part of the year.

Many snowbirds and long-term visitors schedule an annual skin check while they're here — message us on WhatsApp to plan yours.

Frequently asked questions

How often should I get a skin check?

An annual check is recommended, and sooner if you notice a change in a mole or a new lesion that doesn't go away.

Does a skin biopsy hurt?

It's done with local anesthesia, so the procedure itself shouldn't hurt; there can be mild discomfort for a few days afterward.

Is adult acne treated the same as teenage acne?

Not always; causes and treatment can vary by age and other hormonal factors, so an individual evaluation is worthwhile.

Which moles should I pay closer attention to?
Ones that change in size, color, or shape, that bleed, or that look different from your other moles. When in doubt, have a specialist take a look.
